Can Airtronics radio be charged with hitec charger?
If it were my Airtromics (known as "Sanwa" in countries outside of USA) TX, I would simply plug in a Hitec charger and not be concerned.
Copy of my diagram, now used on packaging of a TX.RX and glowdriver AC 3-way charger which is with supplied with an interchangeable TX plug, is attached.
However, as always, this presupposes that your TX has not been amended in any way. In need borrow a multi meter, remove your TX battery then plug charger into TX with TX switch in OFF position, then check olrity of plug into which battery lead is inserted.
